So anything that goes from a higher energy level to 2 is going to be falling within the Balmer series, which is in the visible range of the spectrum.

任何更高能级到2能级2,都是属于Balmer系，它在可见光谱中。

We can plug this in further when we're talking about the visible part of the light spectrum, because we know that for n final equals 2, then that would mean we plug in 2 squared here, so what we get is 1 over 4.

当我们讨论可见光谱的时候,我们可以把这个代进去,因为我们知道n末是等于2的,这意味着我们可以。
